Abstract: ABSTRACT    A method according to the present invention utilizes a data processing means comprising a plurality of data stores, and a temporary store for each such data store, stores for a dimness value and a positional value.  The method determines a particular match between a plurality of events of a query and a plurality of events of a stored data base.  The method utilizes a priorly formed array of data values, each data value representing the number of event positions between the juxta-position of an event in the query and a corresponding event in the stored data base.  A group of one or more data values is provided for each different type of query event.  Each different group is stored in a different data store, with the data values thereof arranged in monotonic order from a first end, preferably with the largest data value at the first end. In the method, the data processor detects the largest data value at the first end of the groups.  The detected data value is transferred from the corresponding group to the corresponding temporary store, replacing a previous data value, if any, in the temporary store.          The data values are then combined to form a dimness value, representing the sum of the absolute values of the algebraic differences taken between the data value which is detected and different ones of the data values existing at the first ends of the groups in the data stores and in the temporary stores.  If the dimness value is smaller than that contained in the dimness value store, the value in the dimness value store is replaced with the newly formed dimness value, and the value in the posi-tional store is replaced with the detected data value.

Abstract: METHOD OF PROTECTING AN ALUMINUM BRAKING SURFACE     ABSTRACT OF THE DISCLOSURE         A method of protecting an aluminum braking surface is disclosed.  A brake lining associated with the surface is formed of a brake lining material which includes as a part of the composition an additive of sodium fluoride or cryolite.          When a brake system composed of the braking surface and the brake lining are subjected to repeated braking actions, the additive of the brake lining reacts with a surface layer of the aluminum braking surface to form a tenacious, wear resis-tant layer thereon.  The additive, upon further braking actions serves to maintain the wear resistant layer as fresh aluminum is exposed during normal wear of the braking surface over its useful life.

Abstract: se No. 4300.225 FREQUENCY SYNTHESIZER TUNING SYSTEM   WITH VARIABLE DWELL SIGNAL SEEK            Abstract of the Disclosure A television tuning system employs a frequency synthesizer system for establishing the tuning of the receiver.  A first programmable frequency divider controlled by a reversible counter is connected between the output of a reference oscillator and a phase comparator to which the output of the local oscillator, after passing through another programmable frequency divider, also is applied.  The phase comparator output is a tuning voltage used to control the tuning of the local oscillator.  A logic circuit responsive to characteristics of the received signals changes the count in the reversible binary counter to adjust the first programmable frequency divider to compensate for channel frequency offsets which may occur in excess of the pull-in range of the AFT discriminator circuit.  To permit operation of the receiver as a signal seek receiver, a pair of signal seek push buttons for the "up" and for the "down" direction, respectively, are provided.  Operation of either of these push buttons functions in conjunction with further logic circuitry and in conjunction with timing circuitry to automatically step tune the receiver channel-by-channel in the selected direction until a channel with a signal present is sensed by the first logic circuit, where-upon the signal seek circuit operation is disabled until one or the other of the signal seek push buttons is reactivated.          The dwell time of the logic circuit for some steps is extended depending upon the relationship of the new channel to the previous channel.  The dwell time also is extended for manual or direct access channel selection.

Abstract: DIAL PULSE DETECTOR          ABSTRACT OF THE DISCLOSURE      A dial pulse detection circuit for partial correction of grossly distorted line current dial pulses, which provides square wave output signals for use by later timing detection circuitry.  To detect such dial pulses, the present invention establishes an upper and a lower detection threshold.  For a valid dial pulse to be detected, the line current must drop through both thresholds, and then rise again through at least the lower threshold.  With the provision of a detection delay following detection of the leading edge of a dial pulse, the presence of a valid dial pulse can be registered.  The present technique used in detecting the presence of dial pulses substantially reduces the chances of rejection of a valid dial pulse which has a grossly distorted waveform.

Abstract: PHN. 9435 ABSTRACT:             A device for receiving analog and discrete input signals and for converting the spectrum thereof without loss of information.  The resultant signal has a frequency response curve which exhibits zero points at the frequency zero and at half the sample frequency. The second zero point is then suitable for addition of a pilot tone, without the required bandwidth being increased and without interference with the data signal. The device comprises two integrating feedback activated. the output signals of which are alternately activated. The sign of the active output signal determines the sign of the input signal of the feedback loops and of the output signal of the device.  One feedback loop directly receives said output signal, while the other feedback loop receives this output signal via a multiplier which alternately receives a positive and a negative multipli-cand.

Pipe is rolled from the rack into a trough which forms part of a stinger. The stinger is nested within a boom and can be telescoped to extend longitudinally away from the boom.  The boom is retracted into nested position within the main framework.  One end of the boom is attached to the main frame by an extensible swing arm apparatus which ele-vates the outer end of the boom while the other end of the main frame is attached to the rig floor by a ramp which moves the other end of the boom from the nested position vertically up-wards and towards the rig floor.  A pipe is rolled from the pipe rack into the trough, the boom is elevated into an inclined position such that the stinger telescopes from the boom to po-sition the box end of the pipe in overlying relationship respec-tive to the derrick floor.  Roughnecks can then pick the pipe vertically upward into the drilling rig and attach the pipe joint to the pipe string located in a borehole.  When coming out of the hole, the opposite procedure is involved in order to transport the pipe from the rig floor back onto the pipe rack.
